• Single
Select Single: Not Distributed for a single base without the ISO+ feature for ISO
communication only among Beltpacs.
Select Single: ISO+ for a single base with the ISO+ feature for ISO communication among
Beltpacs and Auxiliary input and output (Aux In/Out) connections.
• Master / Slaves
If Master and Slave base stations will be used, there can only be one Master base station, with
one or two Slaves. Select Master, Slave 1 or Slave 2, then select the multi-base wiring
configuration; 2-Wire, 2-Wire ISO+ or Aux Dist.
NOTE: Slaves must be configured for the same type of audio distribution as the Master.
• Master
In the 2-Wire ISO+ mode, Beltpacs having a button configured for Talk Aux must transmit on
frequencies for the Master base station for the feature to work.
• Slaves
In the Aux Dist mode, Beltpacs on Slave base stations can only talk on the same channel at
once. If they try to talk on a different channel than the user already talking, they will hear a
busy signal in their Beltpac headset.
Base Station Intercom Configuration:
You can set up intercom configurations from the Configure tab >Edit Base Configuration box
>Base>Config>Intercom Configuration
section:
Select intercom configuration (OFF, 4-Wire Only or 2-Wire/4-Wire) for Channel 1 or Channel 2.
NOTE: If the Mode is set to OFF, the input and output of that intercom will be off. For 2-wire, set to
“2-wire/4-wire.” Both will be active. If set for 4-wire, only 4-wire interface will be active. Even when
“4-wire only” is selected, the line null control(s) on the rear panel must be properly adjusted to avoid
excessive retransmit levels. When 2-wire interfaces are active, the base must be connected to a
terminated 2-wire line.
